CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Korean Patent Application No. 10-2009-0128125, filed on Dec. 21, 2009, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein by reference.

BACKGROUND

1. Field of the Invention

The present invention relates to an image acquisition apparatus and method, and more particularly, to a camera apparatus that may acquire a stereoscopic image, a multi-view image, and a depth image, and a method of controlling the camera apparatus.

2. Description of the Related Art

An existing stereo camera apparatus or a multi-view camera apparatus can acquire images from two viewpoints such as a left viewpoint and a right viewpoint, or from at least three viewpoints. In general, the stereo camera apparatus can acquire a left image and a right image by installing a left camera and a right camera based on a horizontal axis or as a convergence type.

The multi-view camera apparatus may acquire an image by installing cameras for at least three viewpoints, and thus may acquire images from multiple viewpoints.

However, since rectification between cameras is not easily performed and a scale of a camera system is larger than a conventional camera system, changing a location of a camera becomes inconvenient.

SUMMARY

An aspect of the present invention provides a camera apparatus that may acquire a stereoscopic image, a multi-view image, and a depth image by adding, to a stereo camera, a depth information generation function and an intermediate image generation function, and a method of controlling the camera apparatus.

Another aspect of the present invention also provides a camera apparatus that may combine a stereoscopic image and a multi-view image and also combine a single color image and a depth image or a multi-color image and a depth image using a depth image generation function, and a method of controlling the camera apparatus.

According to an aspect of the present invention, there is provided a camera apparatus, including: a camera unit including at least two cameras to acquire a stereoscopic image; a camera control unit to adjust a view angle of the at least two cameras and an interval between the at least two cameras; a depth information obtainment unit to obtain depth information from the stereoscopic image; and an intermediate image generator to generate an intermediate image based on the stereoscopic image and the depth information.

According to another aspect of the present invention, there is provided a camera apparatus, including: a camera unit to acquire a stereoscopic image and a depth image; a camera control unit to adjust a view angle of the camera unit and an interval of the camera unit; and an intermediate image generator to generate an intermediate image using the stereoscopic image and the depth image.

According to still another aspect of the present invention, there is provided a method of controlling a camera apparatus, including: photographing a stereo motion picture by adjusting a view angle of a stereo camera and an interval between an object and the stereo camera; storing a stereoscopic image for each frame by matching a synchronization of the stereo motion picture; performing post-processing with respect to the stereoscopic image; obtaining depth information from the post-processed stereoscopic image; and generating an intermediate image using the post-processed stereoscopic image and the depth information.

According to yet another aspect of the present invention, there is provided a method of controlling a camera apparatus, the method including: photographing a stereoscopic image and a depth image; storing a stereoscopic image for each frame by matching a synchronization between the stereoscopic image and the depth image; and generating an intermediate image using the stored stereoscopic image and the depth image.

EFFECT

According to embodiments of the present invention, it is possible to acquire a stereoscopic image and a multi-view image together or selectively, which is different from an existing stereo camera or a multi-view camera that may acquire only one of the stereoscopic image and the multi-view image.

Also, according to embodiments of the present invention, it is possible to acquire a video image and a depth image of a corresponding viewpoint. Accordingly, it is possible to variously employ a stereoscopic image and a multi-view image for a three-dimensional (3D) TV broadcasting service and the like.
